Retrieving the Red Edge on Earth-like Planets with Heterogeneous Clouds and Surfaces
The detection and characterization of potentially habitable exoplanets is one of the chief goals of astrophysics for the coming decades. Imaging in reflected light is well suited for characterizing Earth-like […]
A Century of Radial Velocity and Astrometric Monitoring of 70 Oph AB: New PFS Data and Constraints on Planetary Companions
At a distance of 5.1 pc, the 70 Oph AB binary star system is one of the most favorable targets for future direct imaging and astrometry missions surveying mature, terrestrial […]
Proton Irradiation of Primitive Atmospheres of Young Exoplanets And Early Earth: N2O Greenhouse Warming And Prebiotic Synthesis
The emergence of habitable conditions on the early Earth and on rocky exoplanets requires persistent energy sources that can drive both prebiotic chemistry and climate warming under magnetically active young […]
Where To Find Other Earths? New List Narrows Down The Targets
New Cornell research – co-authored by an undergraduate and two recent alumni – will help exoplanet scientists pinpoint the most likely places to look for life in the universe out […]
The TOLIMAN Mission: A Low-cost Space Telescope For High Precision Narrow-angle Astrometry
The TOLIMAN project is engaged with the construction, launch and operation of a low-cost space telescope of unorthodox optical design. Its primary science goal targets an exhaustive search for temperate-orbit […]
Constraining Small Planet Compositions for Future Missions
Accurate mass and radius measurements of small transiting exoplanets are essential for probing their compositions, formation histories, and potential habitability.
Spectral Decomposition Reveals Surface Processes on Europa
Competing processes shape Europa’s surface: geological activity replenishes material through resurfacing, while bombardment by charged particles alters surface chemical composition. Each process leaves distinct spectral signatures.
Conditions Suitable For Life On Distant Moons
Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun. A research team from the Excellence Cluster ORIGINS […]
Masses of Potentially Habitable Planets Characterized by the Habitable Worlds Observatory
Constraints on the masses of exoplanets directly imaged and characterized by the Habitable Worlds Observatory (HWO) are crucial for categorizing these planets and interpreting their spectra.
